Filed:

Aug 22, 2002

Appl. No.:

10/225665

Inventors:

Brian Crockett - Wayzata MN, US
Sally Neal - New York NY, US
Robert Sorensen - Maple Grove MN, US

International Classification:

G06F017/60

US Classification:

705/011000

Abstract:

A software based tool provides an assessment of an organization's customer relationship management capabilities. The tool can, in some cases, assign scores to customer relationship management capabilities in response to receipt of input from a user. An assessment is provided of the customer relationship management capabilities based on the scores assigned to the customer relationship management capabilities.

Appl. No.:

11/810540

Inventors:

Rudolph R. Hegel - Richfield MN, US
Robert K. Sorensen - Champlin MN, US

International Classification:

C25C 7/02

US Classification:

204280

Abstract:

A system for the treatment of water to remove metals and undesirable substances from well and groundwater so as to render the water potable is disclosed. The system employs microbubbles of oxygen, which remain suspended in water at a concentration above 100% of the calculated saturated concentration at a particular temperature and pressure. These microbubbles oxidize undesirable substances in the water, which substances include iron manganese, arsenic, antimony, chrome, aluminum, reduced sulfur compounds, pesticide residues, drug metabolites and/or bacteria. Microbubbles are produced by electrolysis or by sparging through a microorifice. A control system for the electrolytic system is disclosed.

US Classification:

205744, 204242, 2042298

Abstract:

Apparatus and related methods for increasing dissolved oxygen levels in water to remove iron and/or manganese. A dissolved oxygen treatment system includes a control system having a power supply and an electrode placed within a water chamber. At the electrode, water is converted into hydrogen gas and oxygen gas, wherein the oxygen gas remains in solution and increases the concentration of dissolved oxygen gas in the water. The dissolved oxygen treatment system can be manually configurable wherein the electrode is selectively wired to use either portions of or the whole electrode based upon testing of the water source with a dynamic electrode test system. Alternatively, the dissolved oxygen treatment system can include a smart controller, a variable power supply and a fixed size electrode, wherein the smart controller continually controls the power output to the fixed size electrode so as to control the amount of dissolved oxygen that is generated.
